Final answer:
To achieve the greatest volume in a permanent wave set, use larger rods and place them on-base. Maintain consistent tension and consider the section size for optimal lift, without neglecting hair health.
Step-by-step explanation:
To create the greatest volume in a permanent wave set, rod placement is key. The size of the rod is directly proportional to the size of the curl; smaller rods create tighter curls, while larger rods result in looser waves and more volume. To maximize volume, stylists often use larger rods and place them perpendicularly to the scalp in a technique known as on-base placement. This method positions the rod directly on its base with the hair wrapped over it, lifting the hair away from the head and thus creating more volume when the hair is styled.
Another important factor is the tension used when wrapping the hair around the rods. Consistent and firm tension can help in achieving an even curl pattern, which contributes to overall volume. Additionally, the section size of the hair being wrapped around each rod can also impact the result; smaller sections with larger rods can produce more lift and volume as opposed to larger sections that might weigh down the hair. It's important to combine these techniques with a proper understanding of the hair's texture and condition to optimize the permanent wave and achieve the greatest volume possible while maintaining the hair's health.
